Definitions
- the present invention relates to the use of an electrically conductive carbon material in a catalyst layer for a fuel cell.
- Fuel cells are power generation systems, e.g. by a
- a fuel cell usually comprises a plurality of individual cells stacked one above the other, each individual cell usually comprising a cathode, an anode and a membrane between these electrodes.
- the cathodes and anodes are the catalytically active layers of the individual cells and are also referred to as catalyst layers. They flank on each side of the membrane and contain catalytically active material, which is carbon-supported. As a binder, and also to improve the
- the carbon-supported catalytically active material is usually embedded in an ionomer. Good interaction between the ionomer and the carbon support material is obtained when the carbon support material is modified by nitrogen atoms and thus
- Amide groups, imide groups or lactam groups as functional side groups.
- the disadvantage here is the susceptibility to corrosion and lack of stability of these modified carbon support materials, especially when used in fuel cells, which are operated in dynamic operation.
- the object is achieved by the use of a specific, nitrogen-modified electrically conductive carbon material.
- the carbon material used in the present invention has a carbon lattice comprising carbon atoms and nitrogen atoms. While in the
- the nitrogen atoms are present only as side groups of the carbon lattice, in the carbon material used in the invention, the nitrogen, more precisely one or more nitrogen atoms, is directly integrated into the carbon lattice. In other words, the nitrogen is part of the
- Carbon skeleton (carbon crystal lattice), which advantageously
- Carbon material is part of a catalyst layer for a fuel cell.
- the catalyst layer may be formed as an anode or as a cathode and is in particular formed as a cathode. It includes beside the
- Carbon material at least one catalytically active material and at least one ionomer, wherein the catalytically active material catalyzes a fuel cell reaction.
- the ionomer serves as a binder and can also be used for
- Carbon material is achieved an improvement in the distribution of the ionomer in the catalyst layer. This is due to a good electrostatic interaction between the ionic groups of the ionomer and the carbon material.
- the nitrogen modification of the carbon material in the carbon lattice the carbon material becomes more polar.
- the nitrogen may also be positively charged, for example by protonation during processing of the carbon material to a catalyst ink or
- anionic or at least polar groups of the ionomer such as sulfonic acid groups. This active interaction allows the ionomer to be evenly distributed around the carbon material.
- Carbon material is surrounded by a homogeneous layer of ionomer.
- the catalyst layer is easy to produce.
- a fuel cell comprising a catalyst layer with an ionomer, a catalytically active material and the specific
- Nitrogen-modified carbon material is characterized by a high power density and lifetime, even if it is operated permanently in a dynamic operation.
- the stability of the carbon material and in particular its corrosion stability can thereby be improved efficiently.
- hydrogen atoms and / or oxygen atoms are present, they can be used to saturate the Carbon atoms and / or nitrogen atoms are used in the carbon grid.
- hydrogen atoms can also bind to one or more nitrogen atoms in such a way that the nitrogen atom (s) receive a positive charge.
- a positive charge on the nitrogen atom improves the interaction with the ionomer in the catalyst layer and achieves a particularly homogeneous distribution of the ionomer in the catalyst layer.
- a proportion of nitrogen in the carbon material is advantageously from 0.2 to 1.2 mass% and in particular from 0.3 to 1.0 mass%, based on the total mass of the carbon
- the carbon grid comprises pyridine units and / or pyrrole units. This is probably due to the aromatic nature of the pyridine and pyrrole units, which allows pyridine and pyrrole to be incorporated very well into the carbon lattice, and in particular into a graphite-based carbon lattice.
- Carbon material is provided according to a further advantageous embodiment, that the carbon material is graphitized.
- Catalyst layer 25 to 65% by weight and in particular 35 to 55% by weight, based on the total mass of the catalyst layer.
- the catalytically active material preferably comprises at least one noble metal, platinum being particularly preferred.
- the noble metal can be used as a single metal or in the form of an alloy or a core-shell catalyst.
- exemplary Alloy-based noble metal catalysts comprising PtPd, PtCo and PtNi. The same metals can also form the core-shell catalyst.
- a proportion of catalytically active material, based on the total mass of the catalyst layer, is 0.02 to 0.4 mg / cm 2 and in particular 0.06 to 0.1 mg / cm 2 .
- ionomer selected from sulfonic acid-based thermoplastics.
- sulfonic acid-based thermoplastics such as e.g. PFSA are available under the trade name "Nation” from DuPont or "Aquivion” from Solvay or Asahi Kasei.
- the proportion of sulfonic acid groups improves the interaction with the specifically nitrogen-modified carbon material, so that the ionomer can be distributed particularly uniformly and stably in the catalyst layer.
- a highly stable and well proton-conducting catalyst layer with high catalytic activity can be achieved by the further advantageous development in which a weight ratio of ionomer to carbon material is 0.2 to 1, 0 and in particular 0.25 to 0.70. If the weight ratio is in this range, a homogeneous distribution of the ionomer around the
- a particularly uniform layer of ionomer is formed around the carbon material. In other words, therefore, the carbon material is also uniformly distributed in the ionomer.
- Figure 1 is a schematic view of a section of a
- Figure 2 is a schematic representation of a catalyst layer according to an embodiment of the invention.
- Figure 1 shows in detail a section of an electrically conductive
- Carbon material 1 which according to the invention is used in a catalyst layer for a fuel cell, wherein the catalyst layer comprises, in addition to the carbon material 1, at least one ionomer and at least one catalytically active material.
- Figure 1 shows a section of the carbon mesh 2 of the carbon material 1, wherein the carbon material 1 is graphitized.
- the carbon lattice 2 in this case has mainly sp 2 -hybridized carbon atoms 3 and, for example, a nitrogen atom 4.
- the nitrogen atom 4 is embedded directly in the carbon grid 2, so it is part of the same and is thus permanently stable and degradationsgesimilart integrated into the carbon grid 2 and not only part of a side group on the carbon grid 2.
- Nitrogen atom 4 is incorporated in the carbon lattice 2 in the form of a pyridine unit 5, in this case in the form of a pyridine ring, for example.
- the pyridine ring fits very well into the carbon lattice 2 as an aromatic, and thus because of its planarity.
- a certain polarity is introduced into the carbon material 1, so that a distribution of the ionomer in the catalyst layer is improved and, in addition, a stability of the carbon material 1, in particular with regard to degradation reactions, such as, for example, corrosion reactions, is increased.
- An example of a production specification for the carbon material 1 is given below:
- a graphitized, electrically conductive carbon material e.g.
- Carbon material dried in an oven. Using a
- Tube furnace was 5 g of the oxidized carbon material in a
- the ammonia-treated carbon material was then washed with hot water to remove reaction residues. Subsequently, the carbon material was again oven dried.
- FIG. 2 illustrates a homogeneous distribution of an ionomer 6 in a catalyst layer 7.
- the catalyst layer 7 contains a carbon material 1 on which a catalytically active material 8 is arranged.
- catalytically active material 8 is carbon supported.
- the carbon material 1 is also surrounded by uniform layers of ionomer 6 and, due to the good interaction (in particular Coulomb interaction) between the carbon material 1 and the ionomer 6, in particular is homogeneously surrounded on all sides by ionomer 6.
